VPX3-673 CMOSS/SOSA Aligned Radial Clock LRM for A-PNT
For Assured Position, Navigation, and Timing (A-PNT)
The SWaP-efficient VPX3-673 delivers state-of-the-art technology services, including a GPS/GNSS Receiver, Chip Scale Atomic Clock (CSAC), and an on-board Inertial Measurement Unit (IMU) – all within a single slot.
The VPX3-673 is also ideal for radial clock distribution applications and can provide a server for various low-power timing services. Serving as a low-skew clock master powered by a GPS-disciplined CSAC, the module offers a variety of configurable clock reference sources and support for up to 16 synchronized clock outputs.
- Aligned with CMOSS and SOSA Technical Standards
- Enables Assured Position, and Timing in difficult environments
- Provides server for Radial Clock distribution applications
- Delivers high-performance capability in 3U footprint
Aligned with SOSA & CMOSS
Choose from variants to support your specific requirements, including models developed in alignment with The Open Group Sensor Open Systems Architecture™ (SOSA) Technical Standard 1.0 and the C5ISR/EW Modular Open Suite of Standards (CMOSS).
Enables Assured Position, Navigation, and Timing in Difficult Environments
The VPX3-673’s onboard 10 degree of freedom IMU makes it capable of precise motion tracking in a denied or untrusted GPS environment. Support for an onboard GB-GRAM type II GPS with SAASM or MCODE support is provided, including dedicated zeroize and keyfill functionality. An RS-232 port and RF 1 PPS input are provided for interfacing with an external RS-232 GPS sources.

What is Assured Positioning, Navigation and Timing?
The potential vulnerabilities of the military’s dependence on Global Positioning System (GPS) and Global Navigation Satellite System (GNSS) data are driving demand for new deployed approaches for detecting threats. In GPS/GNSS-denied environments, ensuring accurate Positioning, Navigation and Timing (PNT) information is delivered to the warfighter is absolutely critical.
Simplifying integration & ensuring user confidence
Designing and developing an A-PNT solution that seamlessly integrates information from multiple complementary sources and provides the same level of performance as GPS is not an easy task. From a design and engineering perspective, there are – quite literally – a lot of moving parts to consider and combine to arrive at a PNT truth. This white paper explores the challenges involved in developing effective and reliable A-PNT solutions, and provides guidelines for taking a holistic approach to A-PNT for maximum effectiveness.
